Yellowbottle , i would definitely not go on another cycle if i were you heres my reasoning:Most of us as im sure you are aware know that using anabolic steroids (alcohol;dugs and high levels of stress also cause disruption of the HPA axis through similar mechanisms, but i will use anabolic steroids in this article for example) worsens your psychology problems by disrupting your HPA axis . Most people believe that the reduction in testosterone is to blame , but this is only a very small part of the problem. Rather the major cause is due to the disregulation of the stress response within the HPA axis. Most of us know that anabolic steroids prevents cortisol from binding to its receptor sites. Although this is great for muscle building it is terrible for our stress respone system as cortisol is an integral part of this system and is ultimately used to de-activate our stress response.
You see it works like this ,once we are placed under stress the hypothalamus in our brain sectretes CRH Corticotropin Releasing Hormone(or Factor) this in turn stimulates the pituitary to release ACTH Adrenocorticotropic Releasing Hormone which in turn stimulates the realease of Cortisol from the adrenal glands. The blood cortisol level then rises , until it reaches a certain level at which point it deactivates the secretion of CRF thus completing the Negative feedback loop . Whilst taking anabolic steroids cortisol is prevented from completing the cycle ,as such the CRH remains activated. This would explain the "on cycle" anxiety as CRH is pro-inflammatory (anxiety can be described as a pro-infammatory reaction), whereas cortisol (which is being prevented from doing its job) is anti-inflammatory .This is the reason why they they give people with asthma a corticosteroid inhaler , (asthma like anxiety is a pro-inflammatory reaction which can actually be brought on by anxiety which would explain the connection) to complete the loop, which to me is like pouring fuel on the fire due to the subsequent immunosuppression but thats another story altogether.
Post cycle the cortisol is allowed to bind to its receptor sites, but the build up of CRH and ACTH results in the dreaded cortisol backlash .It can damage the hypothalamus (ironically the system that controls it) causing atrophy and dampening its response to cortisol ie The disregulation of the HPA axis as the dampend response of the hypothalamus results in constantly activated CRH and subsequent high levels cortisol . The CRH is responsible for the anxiety and the cortisol is responsible for depression (as it interupts the synthesis of serotonin) . This would explain why you are either anxious or depressed ie. either the cortisol is inhibiting the hypothalamus or it is pumping out too much anxiety causing CRH. ie your HPA axis is either over-activated or underactivated, and why everything seems to slow down when you are depressed or speed up when you are anxious.
